Abstract

A device for detecting leakage of a tube section (10) communicating with atmosphere at a first end comprises means (12) for filling said tube section from a second end with a known gas. Pump means (14) are arranged for conveying the resulting gas contents between said ends back towards and through said second end. Gas concentration measuring and recording means (15) are located at said second end for recording the concentration of said known gas in said gas contents with respect to time.
